In Australia, the 90mm stormwater comes in grey, green or white. The green is the recycled product, and is becoming more common. The grey looks better, so it pays to ring ahead to see if it's in stock

If you a confident that you will only be building one speaker, you can buy short (1metre or 3m) lengths of some sizes from Bunnings.

If you have the merest suspicion that you might build others later, I would suggest you buy a full length (6m). Usually, the best place to buy it is from the trade desk of your local plumbers supplier, although the most recent lot of 6inch pipe would have been cheaper at the local hardware store, so shop around!
